我正在将JPA(Hibernate)与spring mydomain类一起使用java.util.Date，但是我已经使用手写查询创建了表...

I am using JPA(Hibernate) with spring mydomain classes uses java.util.Date but i have created tables using handwritten queries...

这是我的创建语句

CREATE TABLE ContactUs (id BIGINT auto_increment, 
                        userName VARCHAR(30), 
                        email VARCHAR(50), 
                        subject VARCHAR(100), 
                        message VARCHAR(1024), 
                        messageType VARCHAR(15), 
                        contactUsTime datetime, 
                        primary key(id))
                        TYPE=InnoDB;

以下代码刚刚解决了这个问题:

The following code just solved the problem:

java.util.Date dt = new java.util.Date();

java.text.SimpleDateFormat sdf = 
     new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

String currentTime = sdf.format(dt);

此' currentTime '已插入类型为DateTime且成功的列中.

This 'currentTime' was inserted into the column whose type was DateTime and it was successful.
